Yep Level...

Most shower bases do have drains in the middle (you can custom order
left or right drain too for those instances where you are ripping out a
bathtub)

But with a center drain unit you need to make sure it is perfectly
level!
Why you ask? Easy one, the angle that it drains towards the center is
not that steep at all. If you set it in and its off, it'll just pool
on one side and drain well on another. So what is normally done is
1x2's are used on the left and right side of the base. Make sure how
you set it up is nice and level. Once done pick up the base and make a
structolite donut. Careful not to put too much around the center (dont
want it squishing around and up the drain (never get the rubber seal to
work then))

Put down the base, pressing it slowly down until it rests on the 1x2's.
Take your last look at the level and let it dry. If you like you can
even take a 1 foot level and read it from a few areas around the drain.
Cheap are ya? then take a cup of water and make sure it flows towards
the drain.

No pooling? no problem!

P.S. make sure to cover that acrylic base when you working with tiles
etc.
Acrylic is not very scratch resistant. Sucks scratching it up before
its first offical shower.


Hi,
Level? drain is in the center and water should flow towards it, level
base?
